What is your most desired firmware improvement for the E-M5?

I'd love to have the camera remember my desired settings for each lens.  So when I switch from the 12mm to a long lens IS automatically comes on, iso goes to some high fixed value, switches to A priority, etc.; and when I switch back IS automatically goes off, ISO gets set to 200, etc.

It's far easier to customize from a constant, known starting point than to have to remember everything you set up on the current lens.
